ArcGIS Runtime SDK for iOS

Support for the web scene specification

ArcGIS Runtime SDK provides partial read support for the Esri web scene specification. This page describes support for web scenes and associates web scene features with classes.

This release of ArcGIS Runtime does not support persistence (write, edit, save or upload) of web scenes.

Scenes

ArcGIS Runtime supports basic features of global scenes, including basemaps, ground surfaces, operational layers, initial viewpoints, tables, and spatial references. It does not support local scenes, environment (lighting) settings, app metadata, presentation slides, clipping, range info, or vertical coordinate systems.

The following layers are either not supported or not supported in scenes:

  • CSV layer
  • Group layer
  • PointCloud layer
  • VectorTileLayer - supported but will not display in scenes

Renderers

ArcGIS Runtime only supports a subset of renderers consumed through web scenes.

Visual variables are not supported on any renderers.

The following renderers supported by the web scene specification are not supported by ArcGIS Runtime:

  • All PointCloud renderers (ArcGIS Runtime does not support point clouds)
  • Raster ClassBreaks renderer
  • Raster Stretch renderer
  • Raster UniqueValue renderer
  • UniqueValueFromStyle renderer

Symbol layers

ArcGIS Runtime supports reading and rendering symbol layers. However, there are no API types available for manipulating these.

The following symbol layers are supported:

  • FillSymbol3DLayer
  • IconSymbol3DLayer
  • LineSymbol3DLayer
  • ObjectSymbol3DLayer

The following symbol layers are not supported:

  • ExtrudeSymbol3DLayer
  • PathSymbol3DLayer

Elevation sources

Runtime supports the ArcGISTiledElevationServiceLayer from the web scene spec, which is exposed as AGSArcGISTiledElevationSource.

The following table associates elevation source properties with the equivalent ArcGIS Runtime types:
